meta-emenlow: move to meta-intel repo from poky repo
This is the meta-emenlow layer, moved from the poky repo in order to
keep all the meta-intel BSPs together.
This version builds against laverne (0.90) - detailed build
instruction can be found in the README file.

| 1 | This README file contains information on building the meta-emenlow | ||
| 2 | BSP layer using any of the supported machine configurations, and | ||
| 3 | booting the images contained in the /binary directory. | ||
| 4 | |||
| 5 | If you're only interested in booting the images in the /binary | ||
| 6 | directory of a BSP tarball you've downloaded, there's nothing special | ||
| 7 | to do - the appropriate images are already in the /binary directory | ||
| 8 | depending on which BSP tarball you downloaded. | ||
| 9 | |||
| 10 | Please see the corresponding sections below for details. | ||

| 20 | I. Building the meta-emenlow BSP layer | ||
| 21 | ======================================= | ||
| 22 | |||
| 23 | The 'meta-intel' repository contains multiple branches, one | ||
| 24 | corresponding to each major release starting with 'laverne' (0.90), in | ||
| 25 | addition to the latest code which tracks the current master. | ||
| 26 | |||
| 27 | In order to build an image with BSP support for a given release, you | ||
| 28 | need to check out the 'meta-intel' branch corresponding to the release | ||
| 29 | you're building against e.g. to build for laverne (0.90), check out | ||
| 30 | the 'laverne' branch of both poky and 'meta-intel'. | ||
| 31 | |||
| 32 | Having done that, and assuming you cloned the 'meta-intel' repository | ||
| 33 | at the top-level of your yocto build tree, you can build an emenlow | ||
| 34 | image by adding the location of the meta-emenlow layer to | ||
| 35 | bblayers.conf e.g.: | ||
| 36 | |||
| 37 | yocto/meta-intel/meta-emenlow \ | ||
| 38 | |||
| 39 | To enable the emenlow layer, add the emenlow MACHINE to local.conf: | ||
| 40 | |||
| 41 | MACHINE ?= "emenlow" | ||
| 42 | |||
| 43 | You should then be able to build an emenlow image as such: | ||
| 44 | |||
| 45 | $ source poky-init-build-env | ||
| 46 | $ bitbake poky-image-sato-live | ||
| 47 | |||
| 48 | At the end of a successful build, you should have a live image that | ||
| 49 | you can boot from a USB flash drive (see instructions on how to do | ||
| 50 | that below, in the section 'Booting the images from /binary'). | ||
| 51 | |||
| 52 | |||
| 53 | II. Booting the images in /binary | ||
| 54 | ================================= | ||
| 55 | |||
| 56 | This BSP contains bootable live images, which can be used to directly | ||
| 57 | boot Yocto off of a USB flash drive. | ||
| 58 | |||
| 59 | Under Linux, insert a USB flash drive. Assuming the USB flash drive | ||
| 60 | takes device /dev/sdf, use dd to copy the live image to it. For | ||
| 61 | example: | ||
| 62 | |||
| 63 | # dd if=poky-image-sato-live-emenlow-20101207053738.hddimg of=/dev/sdf | ||
| 64 | # sync | ||
| 65 | # eject /dev/sdf | ||
| 66 | |||
| 67 | This should give you a bootable USB flash device. Insert the device | ||
| 68 | into a bootable USB socket on the target, and power on. This should | ||
| 69 | result in a system booted to the Sato graphical desktop. | ||
| 70 | |||
| 71 | If you want a terminal, use the arrows at the top of the UI to move to | ||
| 72 | different pages of available applications, one of which is named | ||
| 73 | 'Terminal'. Clicking that should give you a root terminal. | ||
| 74 | |||
| 75 | If you want to ssh into the system, you can use the root terminal to | ||
| 76 | ifconfig the IP address and use that to ssh in. The root password is | ||
| 77 | empty, so to log in type 'root' for the user name and hit 'Enter' at | ||
| 78 | the Password prompt: and you should be in. | ||
| 79 | |||
| 80 | ---- | ||
| 81 | |||
| 82 | If you find you're getting corrupt images on the USB (it doesn't show | ||
| 83 | the syslinux boot: prompt, or the boot: prompt contains strange | ||
| 84 | characters), try doing this first: | ||
| 85 | |||
| 86 | # dd if=/dev/zero of=/dev/sdf bs=1M count=512 | ||
